CHANGE-MAKING MACHINE.

Specification of Letters Patent.

T 0 all whom it may concern: 1

Be it known that I, ALLAN CoATs, a sub j ect of Great Britain, and a resident of Newark, in the county of Essex and State of New J ersey, have invented certain new and useful Improvements in Change- Making Machines, of which the following is a specification.

The objectsof this invention are to secure a simple change making machine of great reliability; to reduce the number of keysor finger pieces to a minimum, and so arrange them that one or a plurality can be operated with a single pressure; toprovide a slide which will not cramp or stick; tosecure a simple and inexpensive construction, and to obtain other advantages and results as may be brought out in the following description.

Referring to the accompanying drawings, in which like figures of reference indicate the same parts throughout the several views,

Figure 1 is a front elevation of a simple form of my change making machine having a single bank of keys;

Fig. 2 is a plan of the same;

Fig. 3 is a section on line A-A Fig. 2;

Figs. 4 and 5' are plan and sectional views respectively, of the machine with'horizontal keys instead of vertical as shown in Figs. 1, 2 and 3; t

Fig. 6 is a plan of the machine with the banks of horizontal keys and the arrangement of money tubes correspondingly changed; 7 V

Fig. 7 is-a perspective view of one of the slides;

Fig. 8 is a front elevation of two banks of vertical keys, and

Fig. 9 is a sectional view, similar to Figs. 3 and 5, illustrating the two banks of vertical ke 5.

Int e specific embodiment of my invention illustrated in Figs. 1-5, inclusive, of said drawings, the body portion of the machine comprises a lower casting 1 providing feet 2, 2 and an interior chamber 3 with an inclined bottom 4 sloping from near the top of the casting at one end thereof to a lower opening 5 at the other end of the machine from which the change is to be discharged. A top 6 closes the chamber 3, and this top provides coin tubes 7, 8, 9, 10 and 11, preferably upright, said tubes being either integral with the to 6 or secured thereto as shown, and prefera 1y slotted longitudinally, as at 12, for convenience in fillin them from the top. At their bottoms, said coin tubes are in open communication with the said chamber 3, except that diametrically opposite ledges 13, 13 project beneath each tube, closely adjacent to the end thereof, from the casting 1, for the pile of coins to rest upon. Said ledges 13 are preferably arranged in a line extending lengthwise of the machine, as shown, and are adapted to support the bottom coin just beneath the plane of the top 6 for the chamber 3.

. Arranged transversely of the base casting 1, so as to slide one across the lower end of each coin tube, is a series of slides 17, 18, 19, 20 and 21, each slide being adapted to. en gage the bottom coin in its coin tube and push the same ofl of the ledges 13, 13 so that it will fall into the chamber 3. As several coins are thus dislodged, they pass down the sloping bottom 4 of the chamber and out of the discharge opening 5, but it will be obvious that this bottom and opening, or indeed the whole lower casting, may be constructed otherwise than I have shown and described to suit various conditions. Each slide consists of a piece of sheet metal 14 in a slideway 15 recessed for it in the top of the'cast- 'ing 1, and having a bent-down portion 16 which works in a saw-cut 22 in the bottom of the slideway 15 and serves as a runner to prevent any cramping of the slide in operation. To limit its range of movement, I have shown each. slideslatted longitudinally, as at 23, to receive a stop 24: projecting from the slideway, but obviously any other equivalent means could be employed. The inner end of each slide is of course adapted to engage the bottom coin of a pile and dislodge it, and the outer end is provided with means for operating it.

In Figs. 1, 2 and 3 the outer end of the slide is simply bent up to form a vertically disposed finger-piece or key 25, for the operator to push against, and for greater convenience and neatness the extremity 26 of this key is bent again at right angles to overlie the top 6. A spring 27 between the key 25 and top 6 then serves to hold the slide normally outward.

In Figs. 4 and 5 the slide is cut ofi at its outer end at the end of the runner and said runner has a substantially vertical slot 28 which receives a pin 29 on the depending arm 30 of a horizontal key 31 fulcrumed to the top 6 as shown. Thus by downward pressure on the key 31 the slide will be pushed in, and a spring 32 arranged between the top 6 and saidarmj30serves to hold the slide normally outward.

I have designated these two kinds of keys as vertical and horizontal, to distinguishjthetwo constructions merely, and they are not to be understood their primary meaning as limiting position; i I

isto be understood that one of the advantages of my machine is that the edges of the keys orv nearly so, whereby two k eys'can bev operated by the pressure of a sin'gle'finger partly, engaging both of them. Thus it bej'noted that with the key boards shown in Figs. 1, to 5 inclusive, any two, adjacent keys can be 'operated with a singleif'finger; In order to extend this to keys 1 may arrange the keys in two rows or'banks one above the otheras shown in Figs. '6, Sand 9. In Fig. 6 there are. two banks of horizontal keys 33 and in Figs; 8' and'9 there are two banks ot'vertical keysseau'ofumm abuttingtedge to edge so that one, two or three keys can be pushed with a single finger tip, and obviously a further extension of my idea would" enable still more keys; tosbe pushed with a single fingertip, In the arrangement of keys in two banks'as shown, I'ha've variedthe arrangement ofcoin tubes s'lig'htly, but it will be obvious that no particular arrangement is essential to the'inventionfi j" j a whatever arrangement my keysare em ployed," lthey are preferably all; in the same plane"or jsubstantially so;
